Python 在Graphviz中生成Pete框架式岩石族树的技巧

我编写了一个简单的python程序（我的第一个！），它接受三个CSV文件——人物、乐队、链接——并生成一个显示“摇滚家族树”的Graphviz点文件，其中人们出现在不同的乐队中，乐队通过不同的阵容。我正在努力接近（尽管它们看起来不会那么好，也不会那么详细）

目前生成的代码如下所示：

digraph Family_Tree {
graph [style="solid", ranksep="0.6", fontname="Berthold Akzidenz Grotesk", fontsize=24, label="Those About to Post-Rock", labelloc="tl", bgcolor="white", fontcolor="black", penwidth="1", color="black", margin=0, nodesep="0.1", splines="polyline"];
edge [fontname="Berthold Akzidenz Grotesk", fontsize=10, arrowhead="none", penwidth="1", minlen="1" ];
node [style="solid", margin="0", fontname="Berthold Akzidenz Grotesk", shape="none", fontsize=20, fillcolor="white"  ];
